SPECIFICATION forming part of Letters Patent No. 480,017', dated August 2, 1892.

Application filed .T une 23, 1886. Serial No. 205,959. (No model.)

To a/ZZ whom it may concern:

Beit known that we, ALFRED C. HOBBs and CHARLES R. RICHARDS, citizens of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Sizing and Polishing Paper Tubes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to produce a machine that will automatically perform the operations of sizing and polishing, which have heretofore been tedious and expensive operations, as each tube required to be manipulated by hand.

With these ends in'view We have devised the novel machine of which the following` description, in connection with the accompanying drawings, is a specification, similar numbers being used in the several figures to denote the different parts of the machine.

Figure 1 is a plan View of the entire 1nachine; Fig. 2, a front elevation; Fig. 3, an end elevation, the yoke being in section, on the line da in Fig. 1; Fig. d, a transverse section on the line b b in Fig. 1, looking toward the left; Fig. 5, a central longitudinal section on the line c c; Fig. G, an enlarged detail sectional View on the line d cl in Figs. 1 and 5, looking toward the left; Fig. 7, a detail sectional view on the line indicated by c in Fig. 5; Fig. 8, a detail sectional view on the line indicated byfin Fig. 5; Fig. il, a cross-section of the tube-holding mechanism, the jaws being shown in their opened position; Fig. 10, a similar view, the jaws being in the closed position; Fig. 11, a plan view, the position ot the parts corresponding with Fig. 9, the cap-plate being removed; Fig. 12, an end elevation corresponding with Fig. 9, the slide being in section on the line o 0in Figs. 1 and 13; Fig. 13, a section of the tube-holding mechanism on the line p p in Fig. 14; Fig. 14, a section on the line 1 q in Fig. 9, looking down; Fig. 15, a section on the line 7c 7o in Fig. 1; Fig. 16, a section on the line l Z in Fig.

1 is the bed of the machine, having ways 2,

3 a carriage adapted to reciprocate in said 7o ways, and 4 plates at opposite sides of the bed, whereby the carriage is held in operative position. The carriage is provided on its under side with rack-teeth, which are engaged by an intermediate gear-wheel 5, journaled in the bed. The intermediate gear-wheel in turn is engaged by a pinion (i on transverse shaft 7.

8 is a driving-shaft journaled in brackets 9,'which are bolted to the bed.

10 is a fixed pulley on the driving-shaft, and 11 loose pulleys on opposite sides thereof.

12 is a straight. belt, and 13 a crossed belt, which run from a main or counter shaft (not shown) to the pulleys on the driving-shaft.

14 is a bevel-pinion on the driving-shaft, which meshes with a bevelgear 15 on transverse shaft 7. The beltshifting mechanism is ot' ordinary construction, consisting of a rod 16, adapted to reciprocate in guides 17. 9o Arms 18 project from this rod and are provided with slots 10 at their outer ends, through which the belts pass.

2O indicates a link, one end of which is pivoted to rod 16,the other being pivoted to a le- 95 ver 21, which in turn is pivoted to a bracket 22.

3 indicates adjustable dogs secured to the carriage, which are adapted to engage the inner end ot' lever 21, which shifts the belt, thus reversing the movement of the driving-shaft roo and moving the carriage in the opposite direetion. As shown in Fig. l the carriage is moving toward the right, the crossed belt being upon one of the loose pulleys and the straight belt upon the iixed pulley. The movement of the carriage toward the right continues from the position shown until the left dog 23 comes in contact with the inner end of lever 2l and carries it toward the right until the straight belt is shifted to the left loose pulley and the crossed belt is shifted from the right loose pulley to the fixed pulley, which of course reverses the movement of the driving-shaft and causes the carriage to travel toward the left. Lever 2l will remain in the position in which it was left when the reverse movement commenced until the right dog 23 comes in contact with it when the movement toward the left is nearly finished and carries it again to the position in which it is shown.

24 denotes yielding buffers against which the ends of the carriage strike at the extremes of its movements, one of said buffers being at the inner end of the bed attached to one of the brackets and the other carried by a yoke 25, attached at the outer end thereof.

The paper tubes during the operation of sizing and polishing are carried by a series of arbors 2G, (in this instance four in number,) which are provided with shoulders 27 and project forward from the side of a disk 2S, to which they are attached. rihis disk is carried by a shaft 29, journaled in bracket 30, which is secured to the carriage. The carriage is provided with a lateral extension 3l, having ways 32, in which a cross-slide is adapted to reciprocate.

34 denotes plates secured to the lateral extension, by which the cross-slide is held in operative position. A stud 35 is adjustably Secured to the cross-slide and projects downward through a slot 36 in the lateral extension. A roller 37 at the lower end of this stud engages an angular cam-slot 3S in the top of a bracket 39, which is secured to the side of the bed. The direction of this slot is straightthat is, parallel with the line of motion of the carriage as the roller first enters it. tion is then inward at an angle toward the carriage, the front end of the slot being straight again-that is, parallel with the line of motion of the carriage. As shown in Fig. l, the cross-slide is at its extreme position outward, the roller being about to enter the inclined portion of the slot. It is of course apparent that as the roller moves down the ineline of the slot the eross-slide will move inward until the second straight portion of the slot is reached, and when the reverse movemeut of the carriage takes place and the roller travels backward in the inclined portion of the slot it will cause the cross-slide to move backward to the position in which it is shown. in which position it will remain until the roller has again entered slot 38 and passed into the inclined portion thereof. The function of this Its direccross-slide is to impart intermittent rotary motion to the disk which carries the arbors.

40 denotes a section of rack-teeth on the cross-slide, which is engaged by a segmentgear 4l, which is journaled on shaft 29, being free to turn thereon.

42 is an ear made integral with the segmentgear, to which a pawl 43 is pivoted.

44 is a curved extension at the side of the ear, to which a spring 45 is secured. This spring acts to keep pawl 43 pressed firmly against a ratchet 4G, which is keyed to shaft 29.

The operation of this portion of our invention is as follows: As clearly indicated in Figs. 1 and 6, the cross-slide is a-t one extreme of its movement, the pawl having moved forward with the ratchet to the limit of its forward movement and having remained there until roller 37 is about to move down the incline again. The effect of the movement of roller 37 from the position in which it is shown in Fig. 1 to the other end of the incline is to move the pawl toward the right from the position in which it is shown in Fig. 7 and to place said pawl in engagement with the next ratchettooth. The return movement of roller37 in the inclined portion of the slot takes place almost instantly. As the ratchet has butfour teeth, the effect of this movementis to carry ratchet 4G forward a quarter of a revolution. As this ratchet is keyed upon shaft 29, it follows that the disk carrying the arbors must move forward a quarter of a revolution. The shaft and arbors are retained in this positionby means of a sliding pawl 47, engaging a holdingratchet 4S, which is also keyed to shaft 29. Ratchet 4S is provided with four notches or depressions, preferably having straight sides, as shown, which are engaged by the end of pawl 47, said pawl being held in engagement with the ratchet by a spring 49. This pawl acts to hold shaft 29 and the arbors against movement in either direction, except when the pawl releases the ratchet to permit the forward movement.

50 is a lever pivoted in a yoke 5], tapped into bracket 30. The upper end of this lever is pivoted to the sliding pawl, and the lower end is provided with a roller 52, which is adapted to engage a cam 53. As the carriage approaches the extreme of its nievement toward the right, as seen in Fig. l, roller 52 engages this cam and as it rides up the incline of said cam forces the lower arm of the lever inward, thus withdrawing pawl 47 from the holdin g-ratchet and permitting pawl 43, which engages the operating-ratchet 46, to carry shaft 2O forward a quarter of a revolution. At the instant this movement is completed roller 52 will have passed backward down the incline of cam 53 and spring 4S) will cause theslidingpawlengaging the holding-ratchet to again lock the parts.

In order to prevent shaft 29, the arbors, the., from moving in either direction during the instant that said shaft is not locked by pawl 47, we have provided a friction-disk 54 at the IOC IIO

end of shaft 29, which is encircled by clamping-arms 55, which are drawn together by nut 56 upon bolt 57, passing through both of said arms.

58 is a friction packing of leather, rubber, or other suitable material, which bears against the periphery of the disk. This device in use is adjusted by means of the nut and bolt, so that it will be tight enough to hold shaft 29 from moving during the instant that it is not locked. Itis not, however, necessary to clamp the disk tight enough to prevent it from moving forward readily when actuatedby pawl 43. As has already been fully explained, each reciprocation of the carriage carries disk 28 and the arbors forward and then backward, and during the forward movement aquarteurevolution is imparted to the disk. During each forward movement of the arbors an nnsized paper tube is forced upon one of the arbors and a sized tube is removed from another arbor. As already stated, for convenience in organizing the machine disk 28 is provided with four arbors, and consequently is made to complete its revolution in four reciprocations of the carriage. Commencing now with the top arbor, (see Figs. l and 5,) suppose that the movement toward the right has been completed and the carriage is moving forward-that is, toward the left. When nearly at the extreme of the movement toward the left, .the forward end of the top arbor will enter a lubricator 59, which is secured to one of the brackets, as will be again referred to. This lubricator consists of a washer or series of washers 60, Which are compressed inwardly by aspring-band 6l and are held in place by a face-plate 62, as is clearly shown in Fig. 5. The washers are kept saturated with oil, so that each time an arbor enters the end thereof becomes thoroughly lubricated. Continuing with this same arbor, as soon as the carriage again reaches its extreme position toward the right and the return movement commencesa quarter-turn of disks 28 and the arbors also commences. At the time the arbors have nearly reached their forward positions again the quarter-turn will be completed. The same arbor already referred to now takes up one of the paper tubes. These tubes (indicated by 63) are placed in a hopper 64 and drop down between the jaws singly when the latter are opened. The feeding mechanism is illustrated in detail in Figs. 9 to I4, inclusive. 65 indicates a bracket by which the feeding mechanism is carried.

66 is a cap-plate by which the parts are held in place and to which the hopper' and lubricator 59 are secured.

67 indicates jaws, which are ad justably secured to plates 68 by means of set-screws passing through slots in the jaws.

69 indicates screwpins, which project downward from plates 68' and carry rollers 70, which engage angular slots 7l in slide 72. This slide is made double-that is, open in the center-eachside being provided with slots 76 is an arm clamped to rod 74, which is adapted to be engaged by dogs 77, adjustably secured to the carriage, when the latter is at the two extremes of its movement. For example, as shown in Fig. 2 the jaws are open and will remain open until the left dog 77 comes in contact with arm 76 in the movement of the carriage toward the right, and when the jaws are closed they will remain closed until the right dog 77 comes in contact with arm 76 in the movement of the carriage toward the left. In Figs. 9 and Il the jaws are shown in the open position, in the latter figure the capplate only being removed. In Figs. 10 and 14 the jaws are in the closed position. In the latter figure the cap-plate, jaws, and plates 68 are removed. It will be seen that the outline of slots 7l in the slide is such that as the slide is drawn out the jaws are closed and as it moves in they are opened. Then the jaws are in their open position, as in Figs. 9 and ll, a single paper tube will drop down from the hopper, pass between the jaws, and will rest upon a bed 78. This bed is made adjustable up and down by means of screws 79, which engage the bracket, and is provided with a V-shaped notch 80, which receives the tubes. The sides of the notch are preferably made straight and are inclined at a right angle to each other. The bearing-faces ofthe jaws are also preferably made in the same manner-that is, straight-and inclined at a right angle to each other. This causes the actual engagement of the jaws and the bed with the tube to be at four lines of contact, which extend the entire length of the jaws. In order, however, to prevent the forward ends of the tubes from being crushed when the arbors are inserted, we have provided a special clamp having a curved inner surface, which grasps the tubes firmly attheir forward ends, passing entirely around them, thusavoiding the possibility of their being crushed when the arbor is inserted. This clamp consists of a` semi-cylindrical piece 8l, attached at the forward end of the bed, and a quadrant-shaped piece 82, attached to each of the jaws. The open position of the clamp is clearly shown in Fig. 9 and its closed position in Fig. lO.

'The diameter of the opening is just sufficient to cause the clamp to press firmly upon the tube without crushing it. As the tubes fit the arbors closely, it of course follows that as the arbors are forced in there will ne a tendency to crush the inner end of the tube. This, however, is wholly prevented by the'clamp. yAs shown in Fig. l,the points of the arbors pass entirely through the tubes, the other ends ofv IOO IIC

the tubes resting against shoulders 27 on the arbors.

83 is a block secured to bracket G5, which is grooved out to receive two vertical slides 84. These slides are forced together at the center by springs 85 at the top and bottom of the block. The block is provided with an opening 86 to receive the ends of the arbors, and the ends of the slides are provided with curved recesses 87, whose length is much greater thanv their depth. These recesses register, as clearly shown in Fig. 12, and form an elongated opening, which permits the pointed ends of the arbors to pass, but against which the ends of the tubes strike, thus forcing them firmly home on the arbors, the other ends coming in contact with the shoulders, as already described. As soon as the tube is firmly seated against the shoulder the forward end of the tube acts to force slides 84E open sufficiently to permit the end to pass through. The jaws open at this instant,thus allowing t-he tube to pass out freely. During the return movement the tube just taken up by an arbor is lubricated by a roller 88, (see Figs. 4 and 15,) which is moved up in contact with it. This roller is carried by an arm 89, which is attached to or made integral with a slide 90, adapted to reciprocate in ways 91, formed in casting 92, which forms the body of the lubricator. This casting is supported upon a bracket 93, attached to the side of the bed. Slide 90 is provided with a longitudinal slot to receive a block 94, the block being made adjustable by a screw, as is clearly shown in Fig. et. This is in order to provide for taking up lost motion and moving the lubricating-roller in or out, if necessary. Motion is imparted to the slide which carries roller 88 by means of a lever 95, carried bya rock-shaft 96, journaled in boxes 97. One ot' these boxes is upon bracket 93 and the other upon bracket 98, also attached to the side of the hed. The upper end of the lever is pivoted to adjustable block 91. Motion is imparted to the rock-shaft by means which we will now describe.

,99 is a crank secured to the opposite end of the rock-shaft, the otherend of the crank being pivoted to a stud 100, which passes throu gh slot 101 in bracket 98 and is screwed into a slide 102, adapted to reciprocate in said bracket.

103 is an arm pivoted near the outer end of the slide, which is provided with a curved slot 104C. A stud 105 passes through this slot and is screwed into the slide.

10G is a face-cam upon the outside of the bed, carried by a shaft 107, which also carries' the intermediate gear 5, from which it receives motion. A roller 108 at the outer end of arm 103 engages the face of cam 100.

109 is a spring, one end of which is attached to an arm 110, projecting from the bed, the other being attached to a pin 111 upon arm 103. The operation of this mechanism is clearly illustrated in Figs. 19 and 20. The

position in Fig. 19 corresponds with that in Figs. 1 and In Fig. 19 the top of cam 106 is represented as moving from the point of viewthat is, from front to back-and roller 108 is resting upon the highest portion of the cam-face. Vhile roller 108 is in this position lubricating-roller 88 is bearing upon the outside of apapertube. As soon as the tube is lubricated, in its movement toward the right roller 108 will begin to pass down the incline on cam 100, which will throw the lubricating-roller back away from theline of movement ot` the arbor. During the movement ot' the carriage and arbors from left to right the intermediate wheel and cam will have made a revolution from left to right from the position indicated in Fig. 2. At the instant the next forward movement ot thc carriage commences the reverse movement of the intermediate wheel and cam 100 will of course commence. In order, however, that this movement shall have no effect upon the slide, we have so constructed the parts that when cam 10G is rotating toward the point of view as seen in Fig. 20 the incline of said cam as soon as it comes in contact with roller 108 will act to swing arm 103 upon its pivot against the power of spring 109 instead of acting to force said slide out, as in Fig. 19. This action of the cam upon arm 103 and slide 102 will be readily understood from the fact that when the cam is rotating from front to back, as in Fig. 19, the incline acts upon roller 108 from above, the tendency being to force the arm down against stud 105. As there can be no movement of the arm, the cam action of the incline upon the roller is brought directly to bear upon the slide to force it out, which oscillates the rock-shaft inward, as seen in Fig. 4., carrying the roller against the tube. lVhen the cam is rotating from back to front, as in Fig. 20, the cam action of the incline upon the roller is from below. The tendency, therefore, is to litt arm 1.03 against the power of spring 109 instead of forcing the slide out, as when the cam rotates in the opposite direction. This ot courseallows lubricating-roller 88 to remain in the same position that it was left by the movement of cam 10G in the oppositedirection. Roller 88 receives the lubricating material from a rolle1'112, carried by a vertical shaft 113, which passes through casting 92 and bracket 93, roller 88 being placed in contact with roller 112 as soon as roller 108 upon arm 103 travels down the incline of cam 10G, as in Fig. 19. Rollers 88 and 112 remain in contact with each other during the forward movement of the carriage and arbors and until another tube is ready to be lubricated in the return movement. A bevel-gear 114 at the lower end of shaft 113 engages abevelgear 115 on a short shaft 110, journaled in bracket 93.

117 is a belt-pulley at the inner end of shaft 110, and 11S is a belt-pulley outside of the bed at the end of transverse shaft 7.

IOC

119 is a beit between pulleys 117 and 11S, through which rotary motion is imparted to roller 112. It will of course be understood that the direction of rotation of roller 112 changes eachl time the large belts are shifted. This, however, does not affect the operation of this portion of our invention.

The lubricating material is placed in a reservoir 120 in casting 92. An opening 121 at the bottom of the reservoir communicates with a passage 122, at the upper end of which is a recess 123, in which the roller 112 lies.

124 is a piston pivoted at the upper end of a rack 125. This piston fits closely 'in the reservoir and is forced downward upon the lubricating material by a weight 126, attached to the rack. The weight is sufficiently heavy to force the lubricating materlal out of the reservoirthrough opening 121 and passage 122 into the recess in which roller 112 lies, so that the latter is kept continually covered with the lubricating material.

127 indicates the cap-plates of journals at the upper end of shaft 113, roller 112 resting between these plates.

12S indicates guardplates, which fit closely to the surface of roller 112 and act to prevent any surplus of the lubricating material from being carried out of recess 123 by the roller.

129 is a drip-cup of ordinary construction.

When it is desired to fill the reservoir, the piston is raised by means of a pinion 130 on a crank-shaft 131. When the rack has been raised sufficiently high to lift the piston out of the reservoir, it is locked in that position by pawl 132. The piston may then be turned back out of the way, resting on pin 133, as indicated in dotted lines in Fig. 4. Thepawl may be locked either in or out of engagement with rack 125 by a spring-rack 134. Turning now to Fig. 20 for an instant, it will be seen that when the pivoted arm is raised by cam 106 it becomes possible for slide 102 to move inward until studlO comes in contactwilh the face of cam 106. 1n order to prevent this, we have provided a stop 135, which projects from the side of the bed (see Fig. 4) and is engaged by a set-screw 136, which passes through the lower arm of lever 95 and islocked at any desired position by a check-nut. Should slide 102 move too far inward, it would of course carry shaft 96 and would throw roller 8S into forcible contact with roller 112. The setscrew and stop just referred toavoid the possibility of any such occurrence.

137 is aspring, one end of which is attached to the lower arm of lever 95 and the other to the bed, the action of which is to draw the lower arm of the lever inward, thus carrying rollerSS against roller 112 until the movement is checked by the stop and set-screw just referred to. In order to prevent the outward movement of slide 90, carrying roller SS, from being too violent under any circumstances, we have provided an air-cylinder 138 under the bed, which is provided with a petcock 139. A piston 140, adapted to reciprocate in this air-cylinder, is pivoted at the end f the lower arm of lever 35, the air in cylinder 138 acting as a cushion to prevent violent movement of the slide. During this second forward movement of the carriage and arbors the second arbor is oiled by lubricator 59 preparatory to taking up a tube at its next forward movement. 141 is a guide attached to bracket 65, through which" the arbors must pass before entering the paper tubes. vThe opening in this guide is sufficiently large to permit an arbor with a tube on it to pass out freely, but at the same time is small enough to insure that the arbors shall only enter the tubes in a right line.

Ve have now described the operations of the different parts of the machine during the first and second reci procations of the carriage and quarter-turns of the disk which carries the arbors. During the third forward movement of the carriage the third arbor is lubricated, the second arbor takes up a second paper tube, and the first arbor, which carries the first paper tube taken up, simply passes forward through an opening 142 in bracket 143, which carries the sizing mechanism, no operation whatever being performed upon it during this reciprocation. Duringthe fourth forward movement of the carriage the fourth arbor is lubricated, the third arbor takes up a paper tube, the second arbor, with the second tube taken up, passes through opening 142, and the first arbor, with the first tube taken up, passes to the sizing mechanism, which we will now describe, referring more especially to Figs. 23 to 26, inclusive.

The sizing mechanism consists, essentially, of an inner shell 144, an outer shell 145, and a chuck 146. The outer shell is journaled in boxes 147 upon bracket 143.

14S indicates the cap-plates.

149 denotes shoulders upon the outer shell, whereby said shell is held against endwise motion, and 150 indicates nuts upon the outer shell for taking up lost motion. Motion is imparted to the outer shell bymeans of abelt (not shown) passing over a pulley 151 upon said shell. I1`he chuck is screwed firmly to the inner end of the outer shell.

152 indicates ways in the end of the chuck, in which the sizing -jaws 153 are carried. These jaws are held in place by a ring 154, secured at the end of the chuck by screws 155, and 156 are set-screws, which pass through said ring and bear against the outer ends of the jaws, whereby they may be adjusted in or outor the-wear may be taken up. VThe sizing-jaws are provided at their inner ends with semicircular recesses 157, which are beveled outward slightly, as shown in Figs. 23 and 24, and which form together a perfectly cylindrical opening, through which the paper tubes pass singly while on the arbors, the sizing of the tubes being accomplished by these jaws, which are caused to rotate at a very high rate of speed, each tube having been previously IOO lubricated externally, as already described. The inner shell extends some distance out beyond the outer shell, serving, however, merely as a guide for the sized paper tubes after they are stripped from the arbors, as will be more fully explained. The in ner shell is firmly heid in place by a clamp 15S, which is secured to bracket 143, the arms of said clamp being drawn togetherin the usual man ner. The inner end of the inner shell is cnt away slightly, as shown, leaving shoulders 1GO.

161 indicates spring stripping-jaws, whose shanks 162 rest against shoulders 16() and are riveted to the inner shell. These jaws are preferably fourin number, as shown in Fig. 2G, and are provided with shoulders ltib, which spring' over the ends of the paper tubes after they have passed through. As each tube euters the stripping-jaws from the sizing-jaws the former open out to allow it to pass freely through, their faces being beveled for that purpose, as is clearly shown. As soon as the tube has passed entirely through both pairs of jaws the stripping-jaws Spring into place over the end of the tube. As clearly shown in Fig. 5 and as already described, the rear ends of the arbors are provided with shoulders 27. These shoulders are sufficiently high to form a stop for the tube, thus preventing it from being forced too far on the arbor, while at the same time the thickness of the tube is about double the height of the shoulder, so that when the tube is in place on the arbor the combined diameter of the tube and arbor is perceptibly greater than the diameter of the shoulder. As soon,therefore, as the tube has passed through the stripping-jaws the latter spring into place and shoulders 163 bear upon shoulders 27 on the arbor, so that in the backward movement of the arbor the sized paper tube is necessarily stripped therefrom. The inner shell has no motion whatever and the tube stripped from the arbor remains just where it was left until forced forward outof the way by the next tube, the inner shell being made sufficiently long to carry the tubes out of the way of the opera tive parts of the machine.

The operation of the entire machine may be briefly summarized as follows: A disk carrying a series of arbors (in the present instance four in number) is journaled on a carriage adapted to reciprocate in ways in the bed of the machine. During each forward movement of the carriage the disk which car ries the arbors is caused to make a quarterrevolution. Starting with any particular arbor, at the first forward movement of the car riage the arbor enters a lubricator, by which its forward end is lubricated preparatory to taking up a paper tube. The tubes to be sized are placed in a hopper and fed downward by gravity. During each reciprocation of the carriage-that is, during the movement toward the left-peculiarly-construeted jaws below the hopper open and permit; a single tube to drop down between them. During the return movement of the carriage-that is, the movement toward the right-the jaws close upon the tube, and at the second forward movement the arbor specially selected enters the tube clamped in the jaws and takes it up, the point of the arbor being forced entirely through the tube, the other end of the tube resting against a shoulder on the arbor. The jaws then open again and allow the arbor to pass forward, carrying the tube with it. During the return movement a lubricating-roller is caused to move forward and lubricate the tube upon the arbor. As soon as the tube is lubricated the roller moves backward and takes lubricating material from another roller, which rotates in a reservoir. At the third forward movement of the carriage the third arbor is lubricated, the second takes up a tube, which is lubricated, as before, during the return movement, and the first arbor, with a tube upon it, merely passes through an opening in one of the brackets to receive it, no operation whatever being performed upon it. At the fourth forward movement of the carriage the fourth arbor is lubricated, the third takes up a tube, which is lubricated externally, as before, on its return, the second has no operation performed upon it, and the first passes between sizingjaws, which rotate about. it at a high rate of speed, being pressed firmly against it. After passing through the sizing-jaws the tube passes through a set of stripping-jaws provided with shoulders, which spring over the rearend of the tube after ithas passed through IOO and rest upon the shoulder on the arbor so Y that when the return movement of the arbor takes place the tube is stripped. off from it, remaining in the shell to which the stripping jaws are attached until it is forced out by the next sized tube. These operations are continuously repeated. As each new tube is taken up by the arbor asized tube is stripped from the one just behind it.

lVe do not of course desire to limit ourselves to the exact details of construction shown and described, as it is obvious that they may be widely varied without departing from the spirit of our invention.
